# 20220303 bkw: Modified by SlackBuilds.org, BUILD=2:
# - fix build on 15.0 (fiddly C++ annoyances).
# - add some JDK detection stuff, to avoid the need to log out and
#   back in after installing zulu-openjdk8, and to make the build
#   fail quickly and gracefully if there's no JDK.
# - binary in /usr/games.
# - absolute paths in .desktop file.
# - install actually useful docs (not LICENSE.html, which had
#   *broken* hyperlinks!)
